According to this article, "3X DVD" which appeared this time is recorded on the existing DVD disc by recording the movie with encryption and video compression technology used in the HD DVD disc, It seems that it will be able to sell video contents of HD picture quality at low cost. For playback you need an HD DVD player.

And the currently marketed Blu-ray and HD DVD uses the same "MPEG-2" video compression technology as DVD, but 3X DVD supports Blu-ray and HD DVD standards , Since the reliability as MPEG-2 is not ensured in terms of picture quality, we adopt a high compression rate video compression technology called "H.264" or "VC-1" which we plan to adopt in the future That means that it has made it possible to record 135 minutes of video with 720p HD picture quality on existing DVD.

I am looking forward to the time when new video compression technology has become full-scale for Blu-ray and HD DVD discs.
